ASSOCIATED PRESS — An Ohio man charged with setting a fire that killed a girl he was accused of raping and her grandparents jumped to his death from a fourth-floor courthouse balcony on Monday, the day before jury selection in his death penalty trial.

Forty-eight-year-old Robert Seman Jr. was being led by deputies from a courtroom after a status conference to a holding cell at the Mahoning County Courthouse in Youngstown when he killed himself, Sheriff Jerry Greene told the Youngstown Vindicator.

“According to a couple of the attorneys and basically everybody there, it seemed like he was in pretty good spirits,” Greene said. “He was talking about the future of his trial, and he just decided to jump.”

The triple murder suspect could have faced the death penalty if convicted in the deaths of 10-year-old Corrine Gump, 63-year-old William Schmidt and 61-year-old Judith Schmidt.

The March 2015 fire at the family’s home occurred the day Seman’s trial in Corrine’s rape was scheduled to begin in Youngstown. Investigators concluded that the fire was fueled by gasoline. Burns were found on Seman’s body after his arrest, prosecutors said.

Seman’s aggravated murder trial was scheduled to begin Tuesday 35 miles (56 kilometers) away from Youngstown in Portage County. Seman’s attorneys successfully argued that he could not get a fair trial in Youngstown because of pretrial publicity.

A Mahoning County judge declared a mistrial last September because a potential juror had prematurely concluded that Seman was guilty and discussed details about the case with fellow jurors.
